In my opinion the only viable Claw classes on higher leveled content are Ninja and Monk. Special Bow Sniper ends up being viable after a while though just not as good as Regular Bow Snipers. Both Ninja and Monk are expensive but have a pretty high potential.
I don't know if you have ever gotten higher leveled or not to see some things other builds have to offer but at 140+ there's tons of variety compared to beforehand and people start to move away from Claw builds at that point unless they are a Monk, Ninja, or Special Bow Sniper.
